T0 at whom it may concern:

Be it known that I, J OsEPH F. BLMSDELL, of New York, (Brooklyn,) in thecounty of Kings and State of New York, have invented a new and ImprovedDumping-Wagon, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improveddumping-wagon for coal, sand, bricks, and other articles and material,the wagon being provided with a hydraulic lifting device arranged toenable the driver to conveniently bring the loaded box or body into anelevated or inclined position to allow of readily dumping the contentsof .the box at a desired place.

The invention consists in such features of construction and combinationsas will be fully described hereinafter and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement with part broken out andwith the box or body elevated. Fig. 2 is a transverse section of thesame on the line 2 2 of Fig. 1, and Fig. 3 is an enlarged side elevationof the tilting device for the box or body.

The wagon on which the device is applied is provided with the usualrunning-gear A and the box or body B, adapted to contain the coal, sand,brick, or other article or substance to be transported from one place toThe box or body Bis pivotally connected at its under side by brackets Cwith a bracket D, attached to the upper end of the plunger E of ahydraulic jack E, having its cylinder E supported by the running-gear A.The pump F for forcing waterinto the cylinder E and raising the plungerE and the box or body B is likewise secured to the runninggear A and isprovided with a handle F under the control of the operator for workingthe pump for the purpose mentioned. A Water-supply vessel G is alsocarried on the running-gearA and is connected with the pump and thecylinder E so that the water from the said supply vessel can pass to thepump and be forced by the latter into the cylinder desired to load thesame the cylinder ll. is connected by a suitable valve and pipe with thesupply vessel G to return the water from the cylinder to the said vesseland to allow the plunger E to descend back into the cylinder. Now by thearrangement described the driver of the wagon by manipulating the handleor lever F can readily work the hydraulic jack E and force the plunger Eupward to lift the box and its contents, and then the box can be turned,as the plunger E is free to turn in its cylinder E so that the deliveryend of the box or body can be brought directly over the place fordumping the contents of the wagon.

The box or body B can be moved into an inclined position after it iselevated, and for this purpose I provide the following device: On theunder side of the body B and at one side of the brackets O is secured abracket H, on which is fulcrumed a toothed segment I, formed at itsinner face with a track I, engaged by a roller J, journaled in a bracketJ, attached to the bracket D. The segment I is in mesh with a segment K,secured on a shaft K, journaled in suitable bearings in the bracket D,and on the said shaft is secured a longitudinally-extending arm Kprojecting at its inner end beyond the front of the box or body to bewithin convenient reach of the op erator. Now when the arm K is swungdown ward the segment K, meshing with the segment'I, causes the latterto move upward, so that a push is exerted against the box-body B at oneside of the pivot-brackets O to move the box or body into an inclinedposition, as indicated in dotted lines in Fig. 1. When the desiredposition has been reached, the arm K is locked in place by a pin L,adapted to engage an aperture in the said arm and aregistering apertureof a series formed in a segment N on an arm formed on or attached to thebracket D. After the load has been dumped the pin L is removed, and thearm .K is swung back to its normal position, so

that the box or body is returned to its normal horizontal position andthen looked in place by the pin L engaging the registering apertures inthearm K and the segment N. If

necessary, the body B is then turned around to be again in alinementwith its running gear A, and then the cylinder E is connected Havingthus fully described my invention, 7

I claim as new and desire to secure by Letters Patent- 1. Thecombination of a support, a Wagonbody mounted to rock thereon, a toothedsegment pivoted to the wagon-body, a roller held by the support andhaving the segment bearing against the same, and a second segment heldby the support and meshed with the firstnained segment whereby to dumpthe Wagonbody.

2. The combination of a support, a Wagonbody mounted to rock thereon, abracket carried by the support, a toothed segment pivoted to thewagon-body and guided on the bracketfand a second segment mounted on thebracket and meshed with the first segment.

3. The combination of a wagon-bed, a hydraulic cylinder supportedrigidly by and located beneath the wagon-bed, a plunger working in thecylinder and capable of extending upwardly above the wagon-bed, awagon-body mounted and rockable on the plunger so that the body may beelevated and tilted to dump the body, and means for creating pressureWithin the cylinder, such means being carried by the wagon-bed.
